Hi kevinmo
For each template we provide a detailed documentation , where all settings are detailed with images and descriptions , you can find details for footer info removal at THIS URL for example
Regarding the add this button it can be hidden simply adding to a custom.css file this code
.addthis-wrap {
display:none!important;
}
If you do not have already a custom.css file in this folder /templates/ja_healthcare/css then create a new one and add your custom code to it.
For any other question we are available through this forum to help you , it is not needed you lost many time to search on forum , many questions are not answered at all , so would be better to ask for help here , we will be glad to help you .
Hope it helps
